# Add Storage Migration

> - Use when changing the shape of any on-device persisted model (session, blueprint/program, feed, exercise-descriptor, ai-plan) or adding a new persisted model — i.e. any edit under app/src/models/storage/versions/, or when a build<...() chain stops compiling because a latest/ type changed. Covers the createMigrations() append-only chain, dependsOn for nested models, and the json-schema regen that must ship with the change.
